Pathobiology of hepatitis delta virus
Journal of Hepatology, 1993Early observations in humans and infectivity studies in the chimpanzee suggested a direct cytotoxic effect as the major pathogenetic factor in delta hepatitis. Data acquired in liver transplant patients, as well as additional experimental and clinical evidence, have modified this view and indicate instead that liver damage depends on several factors ...

In the past few years significant progress has been made in understanding the structure and replication of hepatitis delta (HDV). Some of this work has been recently reviewed (Bonino et al. 1990; Hoofnagle 1989; Taylor 1990a, b). The present chapter will emphasize those areas in which our perspective has recently changed and those questions about HDV ...

Replication of hepatitis delta virus
Journal of Viral Hepatitis, 1996SUMMARY. Hepatitis delta virus (HDV) is a unique viroid‐like human pathogen that is always associated with hepatitis B infection. Replication of HDV involves the transcription of genomic RNA, probably by the host RNA polymerase II, by a rolling circle mechanism followed by self‐cleavage and self‐ligation. Editing of antigenomic RNA, possibly involving

Delta Hepatitis and the Hepatitis Delta Virus
1989Since its discovery in 1977 by Rizzetto and co-workers from Turin, Italy, the hepatitis delta virus (HDV) has become a focus of worldwide interest—interest almost equal to its worldwide importance.1, 2 The delta antigen, which first appeared to be a poorly explained finding of immunofluorescence staining in liver biopsies from Italian chronic hepatitis

Hepatitis Delta Virus Infection and Labrea Hepatitis
JAMA: The Journal of the American Medical Association, 1988To the Editor. —In an interesting article, Bensabath et al 1 suggest that delta virus infection is the preponderant cause of Labrea hepatitis. They declare that the clinical picture of the classic form of massive hepatic necrosis is indistinguishable from the fulminant steatosis observed in Labrea hepatitis.

Delta hepatitis virus infection in ethiopia
European Journal of Epidemiology, 1988The results of Hepatitis Delta virus (HDV) antibody determinations carried on 566 HBsAg positive serum samples from a population of 5270 Ethiopian military recruits are reported. The prevalence of anti-HDV among apparently healthy HBsAg carriers was 5.8%. The prevalence increases with age within the available range (18-30 years).

Delta in Denmark: prevalence of hepatitis delta virus infection
Infectious DiseasesHepatitis delta virus (HDV) infection has an aggressive disease course and is the most difficult to treat of the human hepatitis viruses. In Denmark, as in many countries, the national prevalence of HDV has not been established. Based on diagnoses and laboratory test results in national healthcare registries, we estimated that the prevalence of current

Hepatitis delta virus pathogenicity.
Progress in clinical and biological research, 1993This review has presented data consistent with the hypothesis that HDV may be directly cytopathic or non-cytopathic depending on the stage of infection. Nevertheless, although a majority of HDV-infected patients show evidence of liver disease, healthy carriers of the virus lead to the suggestion that different healthy carriers of HDV can exist, but ...

Hepatitis D virus (HDV) (Hepatitis delta)
1994Infection with hepatitis delta virus is dependent on the simultaneous presence of hepatitis B virus and reaches a maximum in persons with the highest levels of HBV replication. Classification of HDV remains uncertain; distinct from any known human virus, the RNA genome of HDV is similar to that of plant viroids.
